Debrand from O2 to Stock

Hi I am thinking of taking the O2 firmware off my phone and going for Samsung stock. I am on JE2 just now so should I go straight to JE2 stock or the new JE7? The phone is a contract phone so would it be easy to get the O2 ROM back if I ever needed a warranty repair?

SEARCH in development section O2 rom debrand .

Hi
I followed the guide and successfully changed the firmware to the stock Samsung one on the thread mentioned here. However when I did the factory reset and reboot (which wipes everything) I find my handset still thinks it operator is o2 rather than the other CSC code mentioned which should mean it can take the standard firmware ota updates... this was my sole reason for de-branding so i can take advantage of OTA updates without waiting for them via o2.
Everything went as per the guide so I'm not sure why the change to a the XEU CSC operator didnt work. I've tried the factory reset/reboot twice and still shows the same.
Any advice on how to move this forward would be very much appreciated as although I'm now on stock f/w i can't update with KE7 or any of the other recent updates.
cheers
Bob.

Did you do *#272*imei# select csc and then do factory reset? This is what I had to do to get the change to be recognised.
Sent from my GT-I9100 using XDA App

When i enter this I get a screen which shows
Preconfig
Sales Code O2U
Green button (not hilighighted)
and two buttons at the bottom
Install / Cancel
Are you saying i should select this O2U and hit install and THEN factory reset?
-- update --
when i hit the radio button the above screen and hit Install it says 'must be THREE chars.'
So not really sure what to do from here...

BTW CSC currently shows as unknown (from doing *#1234#)
thanks

Hmmm strange. Follow step8 here http://forum.xda-developers.com/showthread.php?t=1064894
If that doesnt work I would put the O2 FW back on and try again

There have never been OTA updates .

Kies does not update stock rom in general though some report it has . Never happened to me from SGS1 to SGS 2 on many tries .
KE7 not yet on Kies for many .
Most of us debrand to remove branding and use Odin to flash stock firmware on release . Odin = KE7 now no wait .
Rebranding phone with original for warranty purpose only if needed .

do a factory reset using setting privacy, my CSC didnt change using the factory reset in recovery menu, only changed when I did the reset in settings menu.

thanks for the replies all. Tried the factory reset from the settings menu but preconfig still shows 02u and *#1234# still shows CSC unknown...
guess I'll have to try reflashing via ODIN again... should i use a different firmware..
i installed
I9100XWKDD_I9100XXKDH_I9100XEUKD1_HOME.TAR
(taken from thread http://forum.xda-developers.com/showthread.php?t=1064894)
Should i try a different version or put the stock one back...from the same thread..
I9100XWKDD_I9100XXKDH_I9100O2UKD1_HOME.TAR
...
I guess whatever i flash I'll do the reset from the boot menu and also the factory reset as recommended..
any further feedback appreciated... guess its not likely i'll brick my phone but would like to be able to take advantage of the new features in the later f/wares.
thanks all.

How to recover my CSC info?

Hi all,
Thank for reading this post.
After I have flashed my branded carrier Vodafone NL -> to the PHN firmware - everything went well. I could boot up set up my account, then when I started to set up my KNOX account, the problems began to appear.
First I could not sign in my KNOX account ... then perform a reinstall of KNOX but ran into an error message telling me "was not able to install because KNOX detected a custom binary" (Phone not rooted). So when I look into ODIN splash screen of the telephone KNOX warranty was ok 0 0x0000). However the letter "b" down below was turned from "0" into "1", this would mean that the binary was changed at some point (well yes, I just flashed to another stock rom).
Anyway, since I need KNOX for work, I had to flashed the Phone back to the Vodafone NL rom. By doing that I was able to get everything up and running again including KNOX. However, when I checked the information I saw that my CSC information was wiped away.
So my question is: I have the Vodafone NL Firmware, when I extract the 5 files, I see a CSC and HOME_CSC file. Is it safe to flash these files via ODIN? Or which files do I need to have in order to get back my CSC information?
In advance thanks for your help.
Cheers!
[UPDATE]
Problem solved - via SmartSwitch - Flashing Original F/W

How to change Region to get update first?

I have a an italian no brand s8 ITV, i want to change in XEU ( uk and ireland) to get update fast more than my country
I flashed all 4 files in odin and then hard reset but nothing changed.. from AQF7 ITV to AQF7 XEU ( try with this to see if i get new update come out in this days) but nothing remain in Phone info and in setting ITV/ITV/ITV nothing change
Is possible without root make this or i wrong something? Thank guys

Did you wipe data / cache after flashing the firmware? I'm assuming that you may have done as you mention a hard reset.

yes i do a factory reset wipe cache in recovery.. but nothing to do nothing change

Flash self with odin you first guy

Ok ITV is part of the same csc as XEU so all you need to do is flash the 4 files but when flashing use the home csc file not the other one and then see what happens.

i try see what happens, i remove sim card too

Nothing with home csc nothing change.. always ITV ITV ITV
Flash, boot set wifi ecc then reboot in recovery ( first say no command all time i tried but 3sec appear recovery) wipe everything, but nothing change

Strange one that. But just thinking because ITV and XEU are part of the csc family you should get OTA pretty much the same time. I just recently updated mine to latest update by connecting my phone to my laptop and then smart switch.

You have to use a UK Sim card and make a reset with it

Change Thai S8 to UK

Hi all,
I'm totally new to Android after taking my iphone for a swim in Thailand (which is completely destroyed). I needed a phone for hotel reservations etc, so I decided to upgrade to an S8, bought at a Samsung outlet in Tesco in Thailand.
I live in the UK, so would like to be able to access all UK features (chiefly of all, Samsung/Android pay - not fussed which), along with not having to pay in Baht in the Play Store. Support have been 0 help, basically telling me I'm SOOL. I've read online about changing the CSC code, but I'd really appreciate some advice about whether this is possible and how I'd go about doing this. I'm not really worried about my warranty as apparently it's not valid in the UK. I'm more concerned about bricking my phone/making it unusable or a pain to operate.
Can anyone help/point me in the direction of an easy to follow guide? I'd be extremely grateful!
My model number is SM-G950FD
Thanks,
Dom

The easiest way is to flash via Odin UK specific firmware. So on Sam mobile I use the EVR firmware for EE UK, they have different ones for the major carriers

OK cool. I'm sure I can find a guide for that, but I have a couple of questions:
- what are the ramifications of this? Will it bork any part of my phone? Are there any other risks I should be aware of?
- will I be able to back up and restore my phone, but with the new firmware?

It will be completely stock you will be fine. In terms of backup & restore the same as you would normally. Naturally you won't have TWRP root etc for proper backup.
but since you want samsung pay to work you cant have those anyway
link to all samsung 950f firmware https://www.sammobile.com/firmwares/galaxy-s8/SM-G950F/
Once you find which you want & assuming your not a member of the site you will get very slow download speeds go here (if you're a member it's really fast)
https://updato.com/firmware-archive-select-model to download.

So I just attempted to flash to BTU. Downloaded the appropriate firmware, then attempted to flash via Odin (BL, AP, CP & CSC (not home)), including a factory reset.
When I restart the device, it reboots in Thai! Any suggestions?
Thanks!

first factory reset. then flash home instead of csc + all the others, should work. If it doesn't change language in the phone first then repeat the steps just given.
You may have a problem only in that because you are not rooted or have custom recovery It defaults to what it was when 1st setup it has frp (factory reset protection). but as I said should work

OK cool - so I've followed these steps exactly and I've ended up with XEU/XEU/THL. Play Store etc still in Baht. Not really sure where to go from here!

Im afraid thats as far as I can help. Without root or twrp. Hopefully someone else will be able to assist

I just tried downloading the 3 UK firmware (my carrier is 3), and I get a 3 boot screen, but the Play Store etc is still in Baht. This is immensely frustrating!

Perhaps if you Google how to reset FRP?

Changing to non-default CSC within MULTI-CSC FIRMWARE

Hi guys,
so I own a non rooted Galaxy S7 edge (exynos) and I am trying to change it's CSC.
Prehistory:
I live in Bulgaria and bought it (back in 2016) from one of the carriers here - Telenor, so naturally it had a Telenor branded firmware (CSC GBL I think). I immediately downloaded the unbranded firmware for Bulgaria (CSC BGL) from Sammobile and flashed it. Phone started in Polish, but didn't have any extra apps or uncotabilities, so I left ti this way.
The problem:
With the new versions of Android the Polish CSC, which the MULTI-CSC for Bulgaria defaults to started having some apps (like samsung pay) that just crash when opened and started having some menus in the settings (like T mobile roaming) which just crash the settings app when clicked. I tried downloading several ROMs (The first Andorid 8.0 and several older Android 7.0) in an attempt to make the phone switch to BGL SCS, but unfortunately whatever I do it just defaults on the Polish one. I tried wiping the cache and factory reset after flash, tried having a Bulgarian SIM card inserted both during flash, cache wipe & reset, and startup, but I cannot change the CSC to BGL.
Notes:
1. Flashing Android 8.0 caused the bootloader to be updated to U2, so I cant flash firmwares with bootloader of U1, unless I flash them without the their bootloader, but this doesn't work everytime (I think)
2. I haven't rooted my phone yet and prefer not to. If I absolutely must I ask for a guide on how to do it without triggering Knox & with option to unroot it after in such a way that it is like it has never been rooted.
3. The Dialer codes for IMEI and CSC change no longer work. I only managed to make the IMEI one ( *#06#) work using a firmware from 07.2017 (flashed without its bootloader), but the one for changing CSC (*#272*<IMEI>#) doesn't work on it.
I'm stuck guys I don't know what else to do. I only want the phone to have a BGL CSC and to receive OTA updates. No root, no nothing.
Thank you for your time.
P.S. I searched the forums all day, but couldn't find a solution

Morning,
I hope you have found a solution to this already. If not.. You need to download a combination file which is the same version as the main firmware you have. eg. XXU2 firmware requires a XXU2 combination file.
Flash the combination file. When the device is rebooted in to factory binary perform a factory reset. now flash the "home csc" file from your main firmware pack. when the handset is powered on again open up the factory imei shortcut/app, this has a keypad type *#243203855# this will bring up the csc codes for your multi-region firmware. select the one you require and the handset will reboot. now just flash your main firmware and it will be the CSC you need.
